in reply to getting non-default dhcp option value

To get custom DHCP options in a Windows client, you will need to make some WIN32 API calls.

From the Microsoft KB article
Windows 2000
The DHCP Client service in Windows 2000 has been updated from Windows NT 4.0. Windows 2000 clients must make a DhcpRequestParams API call to request custom parameters. The DHCP client stores data that is obtained from a DHCP server in its local cache. If the DHCP client cache contains all of the data that is requested in the pRecdParams array of a DhcpRequestParams function call, the client returns data from its cache.

The article contains link to some C code.
